Abstract

A combined warhead arming and drive motor ignition device for a self-propelled missile having a warhead and a drive motor comprises a first acceleration responsive means (1, 2, 3, 4) to provide an output when the missile achieves a first acceleration, a timer initiated by the output from the first acceleration responsive means and providing a first output (i) after expiry of a first period and before expiry of a second period and a second output (v) after expiry of a third period, and a speed responsive means (5, 6) to provide a speed output (ii) when the missile has attained a predetermined speed and also to provide a first distance indication output (vi) when the missile has travelled a first distance but has not yet travelled a second distance and a second distance indication (vi) output when the missile has travelled a third distance. The device also includes gating means to provide an output in response to the receipt of all of the first output (i) from the timer, the speed output (ii) and the first distance indication output of the speed responsive means, ignition means to ignite the drive motor in response to the output of the gating means, and second acceleration responsive…
